Subject: [PATCH] ASoC: SOF: Intel: hda-dai-ops: Split the get_hext_stream() op
 for IPC4

Introduce a separate op implementation for get_hext_stream() for IPC4.
This op will also be used to set the skip_during_fe_trigger flag for the
BE DAI pipeline. With this change, we can remove the flag setting in
sof_ipc4_dai_config() which will further simplify support for
DMIC/SSP/Soundwire in the LunarLake platform.
